According to everything I read, Flash Player should work on Android 4.0.3. I recently updated my Samsung Galaxy s2 to 4.0.3, and Flash content is no longer working on websites I previously had no issues with.
I've uninstalled and reinstalled Flash player from Android Market/"Google Play", no effect. I've tried the built in browser, Chrome and Firefox, same results. When I visit the test page at adobe.com/software/flash/about, instead of reporting back a version number, I just get a grey box with a jigsaw piece in it, saying "looking for plug in" which never finds anything. However in my installed apps, I have Flash Player version 188.8.131.52.
How can I get Flash Player to work on my Android device, as it's supposed to do?
I bought a tablet with the same version of flash. Same results you have, until I downloaded MX Player. Videos now work...
